When she specifically (and correctly) tells the prosecution not to coach witnesses, and then the prosecution willfully does exactly that, her ideology is not the issue (IMHO). I think who appointed her to the bench is, in this case, a convenient dodge for accepting the reality that the prosecution royally screwed up.
The guy is still guilty. Nothing can or will change that.
IMHO it has been decided at the highest level(s) of the US government Moussaoui alive is more important than Moussaoui dead.
